Toyota special functions from the diagnostic session: immo/smart reset, Throttle Learn, ECT reset, ABS alignment, synchronisations and key erase

Every module you can reach in diagnostics offers its own list of special functions, called up with the "Special" button. This guide collects the available functions and what they are for, so you know which module to go into.

Procedure

1. Open the diagnostic session on the module you need and press the "Special" button: the list of functions changes according to the selected unit.
2. IMMOBILISER - "Immobilizer Reset" in the Immobilizer module; "Erase Keys" to erase the keys from the Immobilizer/Smart Module/ECU; "Synchronize" in the Immobilizer module to synchronise the immobiliser with the smart unit.
3. SMART ACCESS - "Smart Module Reset", "Register Key", "Steering Lock Synchronization" (synchronises the steering lock electronics with the Smart Access Module) and "ECU Synchronization" (synchronises the engine ECU with the Smart Access Module), all in the Entry & Smart Access module.
4. REMOTES - "Remote Key Registration" and "Remote Key Deletion" in the Main Body module: this is where you register or delete the remote, not from Key Learning.
5. ENGINE - "ECT reset" to clear the learned ECT values, "Throttle Learn" and "Leave After Sale" in the Engine Control Module. "Leave After Sale" cancels the auto learning (key learning) state of the engine ECU.
6. ABS - "ABS alignment" and "ABS reset" in the ABS module: the learned-value reset is to be used when replacing the ABS module or the YAW rate/G sensor.
7. A/C AND STEERING - "A/C Servo Motor Init" in the Air-condition module and "EMPS Init" in the Power Steering module.
8. GATEWAY - "Gateway reset" in the Gateway module: clears the list of modules fitted to the vehicle, handy when a unit has been removed or added.
